Method

1. Brush the base of a 25x30x5cm/10x12x2in baking or roasting dish generously with butter. Preheat the oven to 190C/170C Fan/Gas 5.

2. To make the fruity layer, place the plums and peaches in a large bowl. Sprinkle over the sugar and cornflour and mix until everything is evenly coated.

3. Pour the mixture into the baking dish and level the surface. Sprinkle over the blueberries and top with the lemon zest, making sure to distribute evenly all over. Finally, scatter over the mint, pushing the leaves in a little so they don’t burn during baking.

4. To make the cobbles, place the butter, sugar and eggs in a bowl and mix by hand or using an electric mixer. Add the flour, coconut and cocoa powder and mix until you have a stiff cake mixture. Add the chocolate chips and mix to combine.

5. Use an ice cream scoop or 2 tablespoons to dollop the cobble mixture sporadically all over the fruit, leaving little gaps in between.

6. Sprinkle the cobbles with a little salt and bake in the oven for 35 minutes, until the fruit is soft, the cobbles are crunchy and you are ready to eat this bad boy! Eat with ice cream and a drizzle of melted milk chocolate, if preferred.
